Carding machine strengthens temperature and humidity control. Grinder A spinning machine that turns fiber strands into rovings. The main function is to draft and twist, and to wind the roving into a certain package to meet the processing requirements of the spinning frame.
The structure of the double twisting unit of the double twisting machine mainly includes the spindle braking device, the spindle part of the double twisting machine, the yarn winding device, and the special device of the double twisting unit. Carding machines are used to process cotton fibers and chemical fibers and belong to textile machinery. According to the spinning process, carding is an important process.
The front process of the carding machine is the opening and cleaning machine, and the latter process is the drawing frame (carding process) or the sliver coiler (combing process). Cotton yarn lowers the temperature, and impurities have a considerable impact. To reduce the raw cotton lap and moisture regain, the impurities are easy to drop, the cotton and silk can be reduced, which should not exceed 8-8.5% of the control lap to regain the cotton and not more than 10 to 11%.
Grooming plants should be controlled to a low relative humidity, usually 55 --- 60%, to allow lap and desorption, increase stiffness and elastic fibers to reduce friction between fibers, and fill with clothing. But if the relative humidity is too low, they pass through static electricity one, and cotton YORK is broken or broken, especially when chemical fiber, this phenomenon is more obvious. On the other hand the reduced moisture regain is disadvantageous after drafting the treated sliver.
Control and reduce impurities in cotton, especially human factors play a positive role, strengthen the maintenance and preservation of driving operations, such as increasing the smoothness of the bottom discharge of the whole card, and the channel cover and other parts, without cleaning work Heat sink car cotton network quality And carry out regular inspection of noil, grasp the machine backward and check in time, which are effective measures to reduce heteroknot. Cards reduce spinning fibers. According to the tightness of fiber cells in sliver spinning, it can be divided into loose cotton spinning and tight neps, and most of the latter studies have some impurities.
A nep is composed of dozens of fiber structures. Most of the enterprises are parenchyma fibers with low correlation coefficient. Such plant fibers have low rigidity and high moisture regain. They are hit by the licker-in teeth on the carding machine. Trade friction affects, and after repeated rubbing between Xinjinlong covers, it is easy to twist into neps. In addition, when the needle teeth of Xinjinlong, Doffer and the cover plate are blunt, the needle teeth hold the fibers poorly, and some different fibers are dissociated between the needle surfaces. , it will gradually form more cotton spinning. Another example is that the transfer of patients from the licker-in to Xinjinlong through the fibers is not good, which makes the licker-in roll back to flowers, and some different fibers are brought back to the cotton feeding board, and the cotton must be rubbed, which will also significantly increase the number of cotton spinning enterprises in my country.
Therefore, it should be checked whether the distance between the licker-in and Xinjin Longyang is too large, and whether the saw blade is hairy or not clean. Xinjinlong metal card clothing will also produce hairy teeth, inverted teeth, rust spots due to crushing, and because the distance between Xinjinlong and Doffer is too large, we will have rounding flowers, resulting in increased neps. When the fiber content of Xinjinlong and Donfankuo is refined, it is easy to increase the neps.
Especially for the elastic card clothing carding machine, the filling of the electronic fibers in the inner ring affects the holding, carding and transfer of these fibers, and the increase of neps is more obvious. For this reason, teachers should try their best to tighten Xinjinlong The distance between the doffer and the doffer, and the needle-copying cycle is reasonably drawn up.
